CULTIVATGR ATTACHMENT.

Specification of Letters Patent.

Patented June 29, 1916.,

Application filed September 18, 1915. Serial No. 51,468.

To all whom it may concern:

Be it known that I, ANDY F. PARKER, a citizen of the United States,residing at Royse City, in the county of Rockwall and State of Texas,have invented certain new and useful Improvements in CultivatorAttachments; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to cultivators, and the primary object of theinvention is to provide means whereby the angle of the cultivatingshovels may be altered, for regulating the depth of insertion into theground, without necessitating the operators alighting from the seat ofthe cultivator, and unloosening various bolts and readjusting theshovel-carrying standard.

Another object of this invention is to provide a cultivator attachmentas specified which is adapted for attachment to any ordinary type ofwheeled straddle row cultivator, which includes a lever and dogmechanism associated therewith, which co-acts with a notched member, forholding the shovel-carrying standard in various positions for regulatingthe depth of insertion of the cultivating shovel, and also by means ofwhich the angle of the shovel may be varied by pivotal movement of thelever.

With the foregoing and other objects in view this invention consists insuch novel features of construction, combination and arrangement ofparts as will be hereinafter more fully described, illustrated in theaccompanying drawings and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters designate like andcorresponding parts throughout the several views, and in which Figure 1is a fragmentary side elevation of a cultivator, showing the improvedinvention attached thereto, Fig. 2 is a fragmentary plan view, Fig. 3 isa fragmentary side elevation of the improved cultivator attachment, Fig.4 is a central section through the attachment, Fig. 5 is a detailperspective view of a part of the attachment.

Referring more particularly "to the drawings, 1 designates thecultivator standard supporting beam, of any suitable type of wheeledstraddle row cultivator, which has secured thereto, at spaced intervalsalong its length, blocks 2. The blocks 2 preferably have their lowersurfaces curved, as is shown at 3, and their upper surfaces flat, forresting against the under surface of the beam 1. The blocks 2 project toone side of the beam 1, and are hollow, having sleeves 5 mountedcentrally therein. The sleeves 5 have bolts 6 extending longitudinallytherethrough, and through plugs 7, which are mounted in the ends of theblocks 2, as is clearly shown in Fig. 4 of the drawings. The bolts 6have eyes 8 formed in their ends remote from the end which extendsthrough the plugs 7. The standards 9, which support the cultivatorshovels 10, extend through the eyes 8 of the eye-bolts (3, and rest inthe substantially semi-circular shaped sockets 11 formed in the pillowblocks 12. The pillow blocks 12 are secured to the outer surface of adisk 13, which is mounted upon the sleeve 5. Each of the disks 13 isprovided with a radially extending recess 1 1, into which the inner endof a hand lever 15 extends. The hand lever 15 has a dog mechanism 16 ofthe ordinary construction, secured thereto, which is automatically heldin a locking position, by means of the spiral sprin 17 The catch or lastend of the dog mechanism 16 is provided for engagement with notches 18,which are formed about the portion of the circular surface of a member19. The member 19 is also mounted upon the sleeve 5, inwardly of thedisk 14, and toward the standard 1. The member 19 has an upstanding arm20 formed thereupon, which is provided with a notch 21. The notch 21extends inwardly from one surface of the elongated arm or head 20, whichis formed upon the member 19, and is provided for receiving a bolt orthe like, which is indicated at 22, and extends through a notch 23,formed in the member 2 1. The member 241 is mounted upon the sleeve 5inwardly of the member 19, and is preferably secured to the end of theblock 2. The member 24 is shaped like the member 19, and is identicaltherewith, in all respects, with the exception of the notches 18, whichare formed in the member 19. The notches 18 are preferably formed in onecorner of the member 19, as is clearly shown in Fig. 5 of the drawings.

VVhen' starting to cultivate grain, the standards 9 may be adjusted toany desired angle for regulating the depth of insertion of the shovels10 into the ground, and during the cultivating operation, if conditionsshould necessitate the changing of the depth of the shovels, thisoperation may be easily accomplished, by releasing the dog mechaandillustratedin the drawings, this Work,

,7 of changing the elevation of the shovels, may be performed withoutnecessitating the row cultivators,the combination, with a cul- *t1vator'standard supporting beam, of blocks V Gopieset this patent may beobtained for removing of anybolts, pins or thelike, and also WltllOUl?the operators allghting from the seat of the cultivator, when theconstruction is used upon a riding cultivator.

While it hasbeen referred to in the specification, as a ridingcultivator, it is to be understood that the invention may be applied toany desired type of walking or riding Cultivators, without departingfrom th'e'spirit of this invention; 7 j

In reducing the invention to practice, certain minorfeatures'ofconstruction, combination, and arrangement of parts maynecessitatealteration, to which the patentee is entitled, 7 providedsuch alterations are comprehended Within the scope of What is claimed[;What is claimed is 1.' In an attachment for wheeled straddle secured tothe beam, sleeves rotatably mounted with said blocks, disks mounted uponthe ends of said sleeves, eye-bolts extending longitudinally throughsaid sleeves, cultivator standards connected to said eyebolts and heldin engagement with the outer surfaces of said disks by said bolts, andmeans operatively connected to said disks for rotating the disks forchangingtheangle of said cultivating shovel carrying standards.

2. In an attachment for wheeled straddle row cultivators, thecombination, with a cultivatin shovel standard carrying beam, of aplurality of blocks secured to said beam, sleeves rotatably mountedcentrally within said blocks, disks mounted upon said sleeves,cultivating shovel carrying standards, eye-bolts connected to saidstandards and extending longitudinally through said sleeves for holdingsaid standards tightly against said disks for movement with the disks, amember mounted upon said sleeves and abutting said disks, said memberhaving a. plurality of notches formed therein, a leier carried by saiddisks, a dog mechanism carried by said lever for co-action with saidnotches, said lever adapted for rotating said disks for changing theangle of said standards.

In testimony whereof I aflix my signature in presence of two Witnesses.
